Woodley, Kristin A.; Goldsbury, Ryan; Kalirai, Jason S; Richer, Harvey B; Tremblay, P.-E.; Anderson, Jay; Bergeron, P; Esteves, L; Dotter, Aaron; Fahlman, Gregory G; Hansen, B M S; Heyl, Jeremy; Hurley, Jarrod

Description

We present a new distance determination to the Galactic globular cluster 47 Tucanae by fitting the spectral energy distributions of its white dwarfs (WDs) to pure hydrogen atmosphere WD models. Our photometric data set is obtained from a 121-orbit Hubble
